HAIR CLIPPER.

pers whenever desired. My invention is di rected particularly to a novel comb as an attachment for hair clippers regardless of the detail construction of the clipper itself, and my comb is formed from one .integral piece of sheet metal machined and bent to form a corrugated base or back member, flanges on the ends thereof to engage with a spring action the ends of the stationary cutter plate of a clipping machine and forwardly extending properly spacedapart teeth set on ,edge for dividing the hair and holding the cutting features of the clipper a predetermined distance from the head or other surface over which the clipper is to be operated. My comb may he slid onto a clipping machine and will be self-holding thereon, no extra part or parts being re-.

quired for securing the comb in place, and

my comb possesses several other advantages among which it may be mentioned that it may be formed from one integral piece of sheet metal, that its features are strong and not at all likely to become distorted or injured by ordinary use or handling, that it presents theminim'u'm contact with the head or other surface over which the clipper is to be operated and that it is highly eflicient for its intended purposes.

The" invention will be fully understood from the detailed description hereinafter presented, reference being had to the ac.cornpanying drawings. in which Fig. 1 is a top view of a hair clipping machine of known type with the comb of my invention applied thereto;

Fig. 2 1s a perspective view of my new comb;

Fig. 3 is a vertical section through the' clipping machine and comb taken on the dotted line 33 of Flg. 1;

Fig. 4 is a front elevation, partly broken awry, of the clippingmachine and comb, an

Fig. 5 is a top view, partly broken away, of a sheet metal blank indicating one stage of the manufacture of the comb and from which the completed comb is formed.

In the drawings 10 designates a hair clipping machine of usual type, and 11 the comb of my invention.

The clipper 10 comprises a stationary base or cutter plate 13, teeth 14 onthe front edge thereof, a reciprocatin cutter plate 15. teeth 16 on the front edge thereof, a top or cover plate 17, a bearing post 18 connecting said base plate and cover plate, a driving crank 19 for the reciprocating cutter plate. a spring 20 for actuating saidreciprocating plate in one direction and operating handles 21, 22, one of which is rigid with the cover plate 17, while the other is mounted for oscillatory movement about the post 18 and is integral with; the crank 19 and pressed against by one end of the spring 20, all the parts just identified of the cutting machine being of known character and not therefore requiring further specific description.'-

The comb 11 is-in one integral piece of sheet metal and comprises a corrugated base 'or back member or plate 23, clip-fianges 24,

25 on the ends thereof and forwardly projecting teeth or fingers 26, 27, all of which are of the same length and stand on edge and have corresponding pointed forward head ends whose upper and lower edges are on diverging curved lines. The teeth 26 are formed at the back of their heads with h00ks'28 and the teeth 27 are formed at the back of their heads with plain vertical edges 29 and otherwise all the teeth 26, 27 are alike.

The teeth 26, 27 are formed from one edge portion of a flat blank. as indicated'in Fig. 5, and then the remaining portion of the blank is corrugated to form the back plate 23 and clip-flanges 24. 25, and in this corrugation of the blank particular care is exercised to have the teeth 26, 27 uniformly stand on edge and project forwardly from corresponding sides of the corrugations, as shown in Figs. 2 and 4, the other sides of the corrugations being caused to stand on uniform parallel planes between the vertical planes of the teeth. By uniformly-corrugattact surfaces, that they materially strengthen -of comb for attachment to clipping mathe comb, that they aid in guiding the instrument from the fact that the hair passes between them and that they allow suficient spring action to enable the flanges 24, 25 to operate as spring clips for securing the comb on the plate 13 of the clipper, it only being necessary in applying the comb to firmly slide it upon the plate 13 until the hooks 28 of theteeth 26 engage the broad end members 30 of the plate 13 and the plain edges 29 of the teeth 27 line up with alternate teeth 14 of said plate, as shown in Fig. 1.

T he employment of a comb as an accessory to a hair clipping machine is familiar in this art and therefore it is not necessary for me to enter into any special details with respect to the general utility of a comb. My invention provides a new construction chines, and the novel features of my comb have hereinbefore been pointed out. The

clipping machine shown without my comb thereon would make a close hair-cut, where- 'as the comb of my invention applied to the machine will ensure a smooth even cutting of the hair at a different and predetermined distance from the head or other surface over which the clipper may be operated. My invention is not limited to any special con- I struction incident to the clipping machine,

all hair-clippers being very much alike as to the two cutting or comb plates, with which my invention is more directly concerned, and differing from oneanother in other mechanical details which are unimportant so far as my invention is concerned.

clipper, said comb comprising 1n one inte- The plates 13, 15' of theclipper are both cutter plates and comb plates, and I have designated the plate 13 as a stationary base or cutter plate so as to avoid confusion with the subject of my invention, which is the comb plate 11. I may also call attention a to the fact that the yielding of the gripping flanges 24, 25 is controlled by the spring action of the adacent corrugations acting at right angles tothe line of the teeth.

What I claim as my invention and desire to secure by Letters Patent, is-

1. A removable comb for application to the stationary toothed'cutter-plate of a hair gral piece of sheet-metal, machined and bent, a longitudinally corrugated horizontal basemember and a series of flat teeth projecting forwardly on edge from oorresponding' clipper, said comb comprising in one inte gral piece of sheet metal, machined and bent, a longitudinally corrugated horizontal basemember and a series of flat teeth projecting forwardly on edge from corresponding sides of the corrugations in said base-member and having heads whose upper and lower edges converge forwardly and which heads at the back thereof align with teeth of,.said stationary cutter-plate, the back of the heads of the end comb teeth being of hook shape to hook over the end members of said outter plate.

4. A removable comb for application to the stationary toothed cutter-plate of a hairclipper, said comb comprising in one integral piece of sheet-metal, machined and bent, a longitudinally corrugated horizontal base member, yielding clip flanges on the side edges thereof to slide upon and grip the corresponding edges of said stationary plate and a series of flat teeth projecting forwardly on edge from corresponding sides of the corrugations in said base-member and having pointed heads which align with alternate teeth of the stationary cutter-plate. I

5. A removable comb for application to the stationary toothed cutter-plate of a-hairclipper, said comb comprising in one integral piece of sheet metal, machined and bout, a longitudinally corrugated horizontal base .member, a series of teeth projecting forwardly on edge from the corrugations in said base-member and clip flanges on the side edges of said base-member adapted with :1 spring action to engage the adjacent edges of said stationary plate, the yielding of said flanges being controlled by the spring action of the corrugations adjacent thereto acting at right angles to the line of said teeth.
